SPECIFICATION forming part of Letters Patent No. 429,210, dated June 3, 1890.

Application filed May 13, 1889. Serial No. 310,568. (No model.)

T0 at whom it may concern:

Be it known that 1, WILLIAM H. FLESHER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in IVindow-Screens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to a new screen for windows, transoms, &c.

The object of my invention is to devise a screen which shall answer the purpose of similar screens and have besides the novel features which I have invented for freeing a room of insects, as flies.

My invention consists of a wire screen having a suitable frame adapted to be fitted and secured to window and transom frames, and where the screen portion of the device has horizontal openings for the passage of insects through the body of the screen, and where the screen parts are so formed in connection with the openings as to enable the insects to pass out of a room, but to prevent their entering through such openings.

Figure 1 is a cross-sectional view of myimproved screen. Fig. 2 shows one partof which the complete section is formed.

My new screen-body is provided with open ings for the exit of the fiies,and which are so made as to prevent the flies'from entering a room by the same openings. These openings may be formed in any practical manner which will furnish the features which I herein show or describe.

Any suitable number of parallel pieces 1 of wire-cloth-such as shown in Fig. 2are used to form the complete body of the screen, and

are arranged and placed by commencing at the bottom of the frame and securing the first piece to the sides 6 of the frame and to the lower frame-bar 8, so that the sides and lower edge 2 of the piece 1 will fit snugly against the frame, and the top edge 3 is inclined outward, as shown. A second piece 1 of wirecloth is then placed above the first with its lower edge 2 directly above the lower edge of the first piece and with its upper edge 3 directly above the upper edge of the first piece. The lower edge 2 of the second piece is placed a little lower than the upper edge 3 of the first piece, so that an opening is made between these two overlapping edges, through which insects may pass upward and outward in the direction of the arrow 9. A fly approaching perpendicularly from either side could not pass through any of the openings, and such an arrangement provides a screen adapted to obstruct vision in lines varying considerably from a perpendicular, thus answering the purpose of a continuous screen for obstructing vision. These openings also facilitate ventilation, while preventing gusts of air blowing straight into the room.

All winged insects invariably ascend and move toward light places in endeavoring to pass out of a confined space, so when they fly against the screen and light upon any part of the screen and crawl upward they find an immediate free passage to the exterior of the room and escape. Insects flying against the exterior of such a screen, when reaching the top edge 3 of one of the cross-pieces 1, would jump onto the next higher one, and so continue until it crawled off the top piece on the frame, and would thus be led away from openings into the room. When such a screen is made of separate pieces, as just described,

they may be attached at their ends to the sides 6 of the frame 6 7 8 in any suitable manner. Fig. 1 shows a groove cut in the inner edge of the'frame and with inclined gaps 4, which permit the pieces 1 to be placed at the proper inclination and be secured at their ends in any suitable manner, as by having their ends tacked in place. The pieces 1 may be cut of proper size from wire-cloth and have their cut edges for the edges 2 and 3; or a piece of wire-cloth may be cut through the middle and one finished marginal edge be used for the edge 2 or 3; or wire strips may be manufactured of the proper width with finished marginal edges for both edges 2 and 3. ires 5, Fig. 2, may be woven in, tied to, or otherwise connected to the edges of the pieces 1, as in making mats, and serve to strengthen the pieces 1 and support them in proper position. For wide windows or transonis it would be preferable to use these wires. \Vhen they project beyond the ends of the pieces 1, as shown in Fig. 2, holes may be made in the insides of the pieces 6, and the pieces 1 sprung so that the wires 5 will enter these holes, and when the pieces 1 are straightened they will be secured at their ends by the proj eotin g portion of the wires 5. The openings of one set of sereen-sectionsare placed opposite the middles of the bodies of theothersets of screen-sections, so that the device will be more effective as a screen and as a means of allowing exit of and preventing ingress of insects, and also of preventing drafts. If an insect should by chance get through the outer section and be confined within the space between the screens, it would endeavor to escape toward the most light and by the upwardly-opening outlet,

and so go out through the screen by whichit entered.

I clai1n A screen for windows and like openings, consisting of a suitable frame, in combination with sets of screen-sections of the kind described attaehed thereto on opposite sides thereof, each set of screen-sections consisting of a series of similar overlapping parallel screen parts havin openings between their adjacent edges and the openings of the adjacent sections being placed so as not to be opposite or on the same level, substantially as set forth.

In testimony whereof I now aifix my signature in presence of two witnesses.
